Moving beach chairs, a beach umbrella, a beach cooler, drinks, food,ice, blankets, and other beach accessories can be very challengingespecially transitioning from hard surfaces onto soft sand. One featureof the present inventive concept is to be able to easily pull a beachwagon cooler right onto the sand from a hard surface, such as a streetor boardwalk.

Referring to FIGS. 1 to 4B, a portable cooler 100 includes a firstsemicylindrical member 101 defining a first side 102 and a second side103. The first semicylindrical member 101 defines a first aperture 104in the first side 102 and a second aperture 105 in the second side 103.The first semicylindrical member 101 defines a space 106. A secondsemicylindrical member 107 is hingedly coupled with the firstsemicylindrical member 101. The first semicylindrical member 101 and thesecond semicylindrical member 107 define a cylindrical member 108 whenin a closed configuration. A cradle 109 is removably positioned in thefirst semicylindrical member 101. The cradle 109 defines a first side110 and a second side 111. The cradle 109 defines a first orifice 112 inthe first side 110 and a second orifice 113 in the second side 111 ofthe cradle 109. The cradle 109 can rotate with respect to the firstsemicylindrical member 101 within the space 106 defined by the firstsemicylindrical member 101. A first wheel 114 is rotatably coupled withthe first semicylindrical member 101 at the first side 102 of the firstsemicylindrical member 101. The first wheel 114 includes a first hub 115and a first aperture 116 defined in the first hub 115. A second wheel117 is rotatably coupled with the first semicylindrical member 101 atthe second side 103 of the first semicylindrical member 101. The secondwheel 117 includes a second hub 118 and a second aperture 119 defined inthe second hub 118. A handle 120 is coupled with the first wheel 114 andthe second wheel 117.

A first axle 121 extends through the first aperture 116 of the first hub115. The first axle 121 also extends through the first aperture 104 inthe first side 102 of the first semicylindrical member 101 and into thefirst orifice 112 in the first side 110 of the cradle 109.

A second axle 122 extends through the second aperture 119 of the secondhub 118. The second axle 122 also extends through the second aperture105 in the second side 103 of the first semicylindrical member 101 andinto the second orifice 113 in the second side 111 of the cradle 109.

In an aspect of the present disclosure, the cylindrical member 108 canrotate about the first axle 121 and the second axle 122 independently ofthe first wheel 114 and the second wheel 117. The cylindrical member 108can also rotate independently of the cradle 109. The first wheel 114 canrotate about the first axle 121 independently of the handle 120, and thesecond wheel 117 can rotate about the second axle 122 independently ofthe handle 120.

Referring particularly to FIGS. 4A and 4B, a threaded bore 401 is formedin each of the first aperture 104 in the first side 102 of the firstsemicylindrical member 102 and the second aperture 105 in the secondside 103 of the first semicylindrical member 101. A threaded member 402is defined along each of the first axle 121 and the second axle 122. Afirst unthreaded member 403 is defined along each of the first axle 121and the second axle 122. A second unthreaded member 404 is defined alongeach of the first axle 121 and the second axle 122. The threaded member402 of the first axle 121 or the second axle 122 is threaded into thethreaded bore 401 to connect the first axle 121 or the second axle 122with the first semicylindrical member 121. Thus, the first axle 121 orthe second axle 122 rotate along with the first semicylindrical member121. The first unthreaded member 403 is position in the first aperture116 of the first hub 115 or the second aperture 119 of the second hub118. The first unthreaded member 403 allows rotation of the first wheel114 or the second wheel 117 with respect to the first semicylindricalmember 101. The second unthreaded member 404 is positioned in the firstorifice 112 or the second orifice 113 of the cradle 109. The secondunthreaded member 403 allows rotation of the cradle 109 with respect tothe first semicylindrical member 101.

In an aspect of the present disclosure, each axle (e.g., axle 121)includes a head 405 and a stop member 406. The handle 120 may bedisposed in space 407 and may rotatably contact the head 405. The stopmember 406 can be employed to arrest longitudinal advancement of thefirst axle 122 resulting from rotation of the threaded member 402 alongthreaded bore 401.

While the first axle 121 is illustrated in FIGS. 4A and 4B, the secondaxle 122 described herein is substantially the same as the first axle121.

In use, when a user unlatches latches 129, 130, the firstsemicylindrical member 101 can open and pivot on hinge 124. When thefirst semicylindrical member 101 is open it rests on handle 120.

Inside of the portable cooler 100 is the separate cradle 109 that rocksfreely and stays relatively level to the ground by rocking on the axles121, 122. Each of axles 121, 122 can be removed (e.g., to disassemblythe portable cooler 100 for storage or transport). The axles 121, 122may extend along the central axis 123 upon which the entire portablecooler 100 can rotate on when it is closed and latched. When the closedportable cooler 100 is being pulled and spinning freely it is controlledby handles 120 and 132.

Cradle 109 will have most of its weight below central axis 123. Cradle109 gets lighter as it approaches the central axis 123 starting from thebottom of the cradle 109 and going higher. Having most of the cradle 109weight under the central axis 123 enables the cradle 109 to rock levelto the ground by rocking on axles 121, 122 within the portable cooler100 when it is closed, spinning freely, and being pulled by handles 120,132. Cradle 109 remains level to the ground with any contents placedinto it as it rocks freely on axles 121, 122.

Cradle 109 can hold both perishable and non-perishable contents and canhold and insulate ice. Ice within cradle 109 is insulated from meltingwhen the first semicylindrical member 101 is closed and is held in placeby latches 129, 130. The first and second semicylindrical members 101,107 may each be double walled and filled with insulating foam fillingwithin sidewalls thereof. When the first and second semicylindricalmembers 101, 107 are closed and latched together it also creates aninsulating barrier from outside temperatures for cradle 109.

There is an insulating seal barrier formed when the first and secondsemicylindrical members 101, 107 are closed and latched together. Theseal creates a barrier from dust, sand, or debris from entering theportable cooler 100 as it spins freely across the ground, sand, orvarious terrain. The insulating barrier also helps in insulating theinterior of the portable cooler 100 from outside temperatures.

The axles 121, 122 can screw in and out of the first semicylindricalmember 101. This allows for a quick release of the handle 120 and of thecradle 109 from the portable cooler 100. Removing cradle 109 fromportable cooler 100 allows for easier cleaning and overall maintenanceof the portable cooler 100.

The entire outer shell (e.g., including the first and secondsemicylindrical members 101, 107) of the portable cooler 100 spinsfreely when pulled by handle 120 and/or handle 132 on axles 121, 122.The portable cooler 100 can be pulled easily onto sand as most of theportable cooler 100 weight will transfer onto the outer shell and willbe distributed uniformly across when making contact with sand. When theportable cooler 100 is pulled from the sand onto any hard surface, theentire weight of the portable cooler 100 is distributed onto the wheels115, 117. The wheels 115, 117 makes it very easy to move the portablecooler 100 along any hard surface. The wheels 115, 117 are each held inplace along central axis 123 by the axles 121, 122.

Handles 120, 132 may be joined to each other by screw knobs 138, 139allowing for quick release of the handles 120, 132 from each other. Whenscrew knobs 138, 139 are loosened, handle 132 can fold into handle 120for space savings during the transportation of portable cooler 100. Whenthe screw knobs 138, 139 are completely removed then handle 132 can beremoved from handle 120 allowing the user to grab the cushioned member133 on handle 120 when lifting portable cooler 100. Handles 120, 132 canalso be joined together to make a bigger handle together by tightlyscrewing the screw knobs 138, 139 through their respective threadedopenings. The bigger combined handle makes it easier to roll the entireportable cooler 100. A bigger combined handle also creates a platform tostrap beach chairs, beach umbrellas, or any other accessories onto theportable cooler 100 while freely moving the portable cooler 100 around.

In an aspect of the present disclosure, at least one latch (e.g., latch129 or latch 130) is coupled with the first semicylindrical member 101or the second semicylindrical member 107. The latch is configured tosecure the first semicylindrical member 101 to the secondsemicylindrical member 107 when in a closed configuration.

In an aspect of the present disclosure, a second space 131 is defined inthe second semicylindrical member 107. The space 131 allows foradditional room within cylindrical member 108 for any objects held inthe cradle 109 to project into second space 131.

In an aspect of the present disclosure, a second handle 132 is removablycoupled with the handle 120. A first cushioned member 133 may beconnected with the handle 120 and/or a second cushioned member 134 maybe connected with the second handle 132. The cushioned members 133, 134can be employed to assist in lifting up or pulling the portable cooler100. As an example, the second handle 132 may be detached from thehandle 120, and the handle 120 along may be employed for lifting up theportable cooler 100.

In an aspect of the present disclosure, an indent 135 is formed in thefirst semicylindrical member 101 and a protrusion 136 is formed in thesecond semicylindrical member 107. The indent 135 receives theprotrusion 136 therein to form a seal between the first semicylindricalmember 101 and the second semicylindrical member 107 when in a closedconfiguration. The positions of the indent 135 and the protrusion 136may be reversed with respect to the first and second semicylindricalmembers 101, 107.
